[PATCH] 2.4: export the symbol "mmu_cr4_features" for XFree86 DRM kernel drivers

[Calum Mackay <calum.mackay@cdmnet.org>]

I'd like to request comments on the appended; proposed patch for 2.4 to
export the symbol "mmu_cr4_features".

This is needed by the XFree86 DRM kernel drivers, since Christoph's
backport of vmap() in 2.4.22-pre7. [some] DRM kernel drivers (e.g. radeon]
refuse to load without this fix, from 2.4.22-pre7 onwards.

cheers,
Calum.
